Product Review

Product Description Toasty Feet insoles contain the insulating material, aerogel - simply the lightest and lowest-density solid known to exist. This nano-technology, used by and developed for NASA, is 50-99-Percent air, yet can hold 500-4,000 times its weight in applied force. What does that mean to you? It means the insulating material does not obtain its effectiveness from loft or thickness - so the insoles' insulating material will not lose its effectiveness when compressed underfoot. Toasty Feet insoles effectively block the transfer of cold and heat - keeping your foot a constant and comfortable temperature. Fits in almost any shoe or boot.
